It is also important that the only TWO numbers that that holds true for are zero and two...........and that there are only two numbers which it does................0 and 2..........2 is the 1st prime.............the 1st prime is 2...........like 1/2.......like the critical line............................

2 + 2 = 4...............2 * 2 = 4.........pi becomes..................44.......if you truncate it at the 3rd number..............why is three imp..................it is the 2nd prime...............AND 2 and 3 are the only primes ever only a digit apart...............................................
